Fig. 1 D-1F and 1H-1J show to lock the fitting-type electrical connection that may include in the locking receptacles of the present invention Clamping device another embodiment working method.In each among the example 500-505 of Fig. 1 D, figure is most Lastrow represents the end-view of clamping device, and most next line represents the side view of clamping device, at this time electric contact pin be in Lower state：1) 500,2 are disengaged) it is inserted into 501,3) it is fully inserted into 502,4) it is fully inserted into 503,5 under tension) release 504 and 6) 505 in contact demolishing process.For exemplary clamping device as referring to figure 1E there are two conduit 606, these conduits to grip contact And the side of the cross-join spring 603 of connecting channel.It should be noted that clamping device can be used as electric contact and clamping simultaneously Mechanism, also can be only as the clamping device for being integrated with independent electric contact.Fig. 1 H-1J show it is a kind of simultaneously as electric contact with The clamping device of clamping device, Fig. 1 F show a kind of clamping device for being suitable for being used in combination with independent electric contact.Fig. 1 H In detailed components include gripping conduit 902, cross-join spring 901, integrated conductor crimping piece 903, release shaft 904, with And release shaft contact block 905.Possible example can be made of a kind of appropriate material or multiple material (such as steel and copper), so that folder The function of holding mechanism, electrically and mechanically characteristic, produceability and cost optimization.Material can be according to passing through any appropriate mode Couple or be locked to and work normally together, such as by mechanical interlock, fastener, gluing etc., so that its function optimizes, And its cost is reduced to the maximum extent.

One possible example is that clamping device is also as by annealed brass or phosphor bronze or other appropriate material systems Into electric contact.Due to the expansion characteristics of the material of selection, electrical prongs from any point of resistance of its connection to insertion (note that Pin can be different shapes, may be, for example, stitch geometry), the heated relevant expansion with holder contact (socket) is (more Say to body, be the expansion of cross-join spring) it can cause to grip the gradual fastening of functional component.Even if the socket in initial be inserted into It is not " locked " on pin (for example, not applying the withdrawal force of anchorage clip handgrip body), and is applied to unique on contact surface Supporting force is the active force of cross-join spring, and when applying electric current, the resistance of the joint of socket and pin also results in one Determine the heating of degree.If resistance is sufficiently high, (such as pin is undersized or is damaged and the contact with conduit differs Cause), then the temperature of component can start to increase.Furthermore it is possible to conduit is manipulated (that is, being connected directly to the conduit of inlet wire and passing through friendship Fork connection spring connection opposing races) between electrical connection section so that have additional heat in higher electric current, from And heats more more than other places are generated at cross-join spring.In in either case, the heated meeting of cross-join spring Cause to expand.Since the connecting line to radiate mainly via the pin of insertion and below carries out, the temperature of cross-join spring Degree can be higher than the mean temperature of pin.Therefore, the expansion of pin is smaller.In certain points, this species diversity can allow by spring The socket of bulging overcomes the molecule latching force (stiction) between conduit and pin edge.Conduit can be moved relative to pin slightly It is dynamic, and form new engagement.At this point, since being slightly close to for newly being formed between conduit and pin connects, resistance can reduce, and whole A device can be begun to cool down.Now, cross-join spring can shorten, and the power for acting on supporting-point between conduit and pin can be by It is significantly increased in tangential force, this is similar with the stress when applying withdrawal force, thus can more efficiently re-form and be electrically connected It connects.And this can further reduce resistance, and effectively on socket " locking " to pin, and ensure good electrical connection, i.e., Make mating surface imperfect.This is a kind of reproduction condition made a response to bad connection, it is intended to carry out certainly bad connection I cures.

Fig. 1 E show the mechanical property of clamping device.Electric contact 600 (or other plug constructions) is inserted into clamping device In 601.Clamping device is sized so that contact struts clamping device.Here, the front end of clamping device is (electric first One end of contact contact) it can turn up, to lock contact, and contribute to the expansion of clamping device.This expansion action is in Fig. 1 D It is shown in 511.Lateral cross connection spring 603 plays the role of resisting the opening of clamping device.This can ensure that electric contact 600 Edge is biased, to contact conduit in predetermined contact point 609.Electric contact and/or clamping device of different shapes have different connect Contact and/or contact surface.In the embodiment shown, the contact point/contact surface for generating clamping action is mainly or entirely located at On the top and bottom of pin rather than as being typically electrically connected situation on side.In order to avoid appointing for electric interface What possible deterioration problem, it may be desirable for this arrangement, certainly, it should be noted that this deterioration is less likely Occur, because chucking power is distributed in very long length and (is likely distributed on the entire width of contact).In electrical contact pin 600 After being inserted into clamping device 601, play a part of extracting any withdrawal force (pulling force) 604 of pin 600 all from clamping device 601 It can cause to apply chucking power F (gripping power) 605 on the side of pin 600.The chucking power is by applying pulling force on conduit 606 Lateral cross connection spring on every side of clamping device effect generation, the effect of spring force causes conduit to press towards each other Tightly.The relationship of power is typically F (gripping power)=F (pulling force)/tangent (angle θ).Therefore, chucking power F (gripping power) is compared with from folder The power F (pulling force) for holding the effect that pin 600 is extracted by mechanism 601 increases soon.So with the power for attempting extraction pin 600 Increase, clamping device 601 on pin 600 grip effect and can become more firm.Once grip mechanism drives hair by pulling force 604 The effect of waving, friction will tend to make to grip mechanism holding securely engagement.If it is desired to release clamp system, needs to push release lever 607, to generate power F (release force) 608.This power can reduce angle θ, and conduit is promoted to be gripped away from each other so as to be reduced rapidly Power F (gripping power) 605, and allow easily from grip mechanism 601 extract pin 600.The release force 608 completed needed for release can It can very little.

With in a kind of relevant possible embodiment of standard NEMA C-13 sockets, lateral cross connection spring can be by Copper or copper alloy are formed, and with about 50/1000-75/1000 inch thickness.In this case, curve 602 can substantially be justified Shape shape has about 75/1000 inch of radius of curvature.Curve 602 may extend into lateral cross connection spring 603, thus The neck radially to narrow is formed in lateral cross connection spring 603.This curve 602 is in addition to there is the working characteristics for gripping mechanism Outside actively impact, moreover it is possible to avoid being likely to become the initial point of crackle or accelerate the wedge angle of metal fatigue.The neck additionally aids more The pivotal point of lateral cross connection spring 603 is limited relative to conduit well.It should be understood that specific works characteristic (such as (but not office It is limited to) the slight amount of movement that allows before locking, act on the total amount of chucking power and position, clamping device release on pin When the size (if there is) of power and the tolerance that is operated for frequent cycle of clamping device) be likely to be dependent on specific application, And it can change as needed.There are many other construction variations and manufacturing technology can be changed these working characteristics.For example, laterally Cross-join spring (or its some part) can reverse (such as with material punching press plane at an angle of 90) as needed, to influence bullet The pivotal point and flexural property of spring.

The selection of material, the thickness of device and geometry and forming mode influence grip the working characteristics of mechanism 601. The spring constant of lateral cross connection spring may be influenced by all these variables.For example, the radius of changeable curve 602, The thickness of the neck of location and shape and cross-join spring 603, to realize different spring constant values.In order to make spring Apply tension fore-clamp grip or the size of the contact with gripping mechanism combination work on the contact in being inserted into holding mechanism Range reaches best, and it may be desirable for this.Note：Tension fore-clamp grip is defined as applying any pulling force 604 on contact It is applied on contact 600 under the action of lateral cross couples spring 603 before and grips power.

G is please referred to Fig.1, another possible example is shown.In this example, the working method of mechanism and (1D To 1F) described in working method it is similar.With between the pulling force 710 on pin 706 and the reaction force 711 of pulling force Component apply tension, the contact pin 706 of the contact point (703,707) of conduit (704,705) and insertion is (note that pin can Have different shape, may be, for example, stitch geometry) at supporting force exponentially increase, pin is caused to be lockked by conduit moment. As pulling force F increases, the tension in cross-join spring 701 also continues to increase.In this example, cross-join spring is crescent Shape, it is different from the linear spring described in Fig. 1 D-1F and 1H-1J.The crescent-shaped allows cross-join spring herein There are two types of act on for tool.First, they with the tie point of conduit (704,705) at have spring effect, secondly, they along intersections The long axis for coupling spring (701) has spring effect.The spring effect of increase along long axis allows cross-join spring to have can be pre- The elongation of survey or expansion service.As pulling force F continues to increase, the tension in cross-join spring 701 also continues to increase, until increasing Start the degree stretched along its long axis to cross-join spring greatly.At this point, apply pulling force 710 in conduit (704,705) Contact point (703,707) and the relationship gripped between power the stopping growth for being inserted into generation at contact pin 706.Now, increase is drawn Power 710 can cause to overcome the friction at contact point 703,704, and the meeting of contact pin 706 relative to conduit (704,705) and grips machine Structure 700 moves.If keeping pulling force 710, contacting pin 706 can completely be extracted from conduit (704,705).This conditions permit Component 700 has in length tension relation there are one predictable point, and in this, plug and socket can separate, and will not damage Critical piece, pin grip mechanism (as previously mentioned, it can grip mechanism as electric contact that this, which grips mechanism, either Mechanism is independently gripped with integrated electric contact).

Fig. 1 D are refer again to, the pin 530 of plug is shown before being inserted into the socket with electric contact 510 Form.Pin 530 can be standard plug (such as 320 plugs of IEC, NEMA5-15 etc.) grounding pin or other pins, and It and can be there are many size and shape.Moreover, the socket comprising electric contact 510 can be standard socket (such as NEMA standard power cord End cap, 320 power cord end caps of IEC etc.) grounding receptacle or other sockets, the socket receive standard plug at work.Institute It states socket and includes clamping device 520, and more than one clamping device can be utilized within an outlet.Clamping device 520 designs To be slided and lock-bit technology using simple.

According to the present invention, other clamping devices are also possible.For example, clamping machine can be provided using woven wire Structure, the form of the woven wire (are referred to as " contact " with reception contact, pin or other plug constructions is sized to.Gold At least one mantle friction for being dimensioned to the contact with being inserted into for belonging to silk screen engages.It is intended to when with after-applied from socket When extracting the power of contact, woven wire stretches, and its section is correspondingly shunk, so as to be clamped on contact.It can use Kellem formulas relieving mechanism loosens the mesh of woven wire, so as to deenergized contact.For example, when gripping cylindric contact, this Kind grips mechanism may be very useful.

Fig. 2 C show a kind of cross section of possible embodiment of locking electrical socket 820.Socket 820 is IEC 320 Type power cord end cap socket, it grips mechanism 828 including one or more.Socket 820, which includes being inscribed, bottoms out plate module 824, institute The inscribed plate module 824 that bottoms out is stated to include gripping mechanism and electric contact 826 and 828.Wiring 836 and 838, which is attached to, grips mechanism On electric contact socket, and pass through power cord 834 and stretch out socket 820.Floor module 824 is attached to power cord strain relief machine Structure 832, when 834 stress of power cord, the power cord strain relief mechanisms 832 prevent power cord detached with power cord end cap from And component is caused to damage.Fig. 2 C show a kind of possible relieving mechanism method of operating.Specifically, be formed as can for socket 820 Stretch mode has the shell 822 slided on floor module 824 and strain relief mechanisms 832.Protruding portion on shell 822 850 engage with the release construction 851 in mechanism 828, its release form mechanism 828 can be bonded to so as to slide shell 822.Figure Clamping device described in 1D-1J can be described in the document with combination many other relieving mechanisms combine.

Fig. 2A -2B show a kind of cross section of embodiment of locking electrical socket 20.Socket 20 is to include locking mechanism 320 type power cord end cap sockets of IEC.Socket 20 includes the inscribed of receiving contact socket 26 and 28 and bottoms out plate module 24.Wiring 36 and 38 are attached on contact socket, and pass through power cord 34 and stretch out socket 20.Floor module 24 is attached to power supply line strain Eliminating machine 32, when 34 stress of power cord, the power cord strain relief mechanisms 832 prevent power cord and power cord end cap point It is damaged from so as to cause component.Spring prong holder 40 is arranged as the surface contiguous with floor module 24, and across socket 20 Pin receiving part 44.One end of spring prong holder 40 is around the inscribed one end bending for bottoming out plate module 24, interior contact base plate Module 24 locks spring prong holder 40 in assembly (under packet mold materials 32).

Alternatively, spring prong holder 40, which can be locked to be inscribed by screw or other fasteners, bottoms out plate module 24 On and/or be embedded in module 24.It is embedded in module 24 or is inserted by the spring that packet mold materials is locked in power cord end cap The part of foot holder 40 can be constructed (for example, by the punching in embedded part and/or edge is made to form sawtooth or with other sides Formula shapes) it is the anchoring strength for improving embedded part.The other end of spring prong holder 40 is held with telescopic locking release Handle 22 contacts.With the clamping device 12 shown in Figure 1A -1C similarly, spring prong holder 40 includes aperture, the hole Mouthful size allow the grounding pin of plug across and into socket 26.The size in the aperture in spring prong holder 40 can Slightly larger than a pin (for example, grounding pin) in standard plug, so as to which the aperture can be as the folder for locking receptacles 20 Hold mechanism.It is appreciated that holding machine described herein can be used in the pin (for example, round pin) with different cross section shape Structure, it is only necessary to be appropriately modified to the geometry of orifice shapes and spring prong holder.For various types of pins Cross section it is variously-shaped, this modification may be specific.The working method of this version and holding described herein The working method of mechanism is essentially identical.Spring prong holder 40 can also take proper shape and construction (will hereinafter more It is described in detail), to prevent from contacting with other pins, and provide required release tension.Moreover, holder 40 can be maintained at mould In embedded conduit in block 24, to further prevent the traversing of holder 40 or move left and right.The following detailed description of spring prong The working method of the clamping function of holder 40.

Fig. 2A shows a case that the locking receptacles 20 when on power cord 34 almost without strain.As shown in the figure, spring is inserted Part in the pin receiving part 44 in socket 20 of foot holder 40 is not at substantially vertical position.With Figure 1A -1C Shown in clamping device 12 working method similarly, when pin is inserted into, this construction in spring prong holder 40 Aperture allow plug pin pass freely through and enter in socket 26.This is because the pin with plug acts on bullet On spring pin holder 40, the position of spring prong holder 40 can be changed into without restriction lies substantially in vertical position It puts.

Fig. 2 B show that locking is inserted when exerting a force along the opposite direction for holding release lever 30 to the power cord 34 of socket 20 The situation of seat 20.This is socket 20 " releasing position ", and in order to be more clearly shown that working method, cooperation is not shown in the accompanying drawings Pin.The action for triggering this position is shown in figures 3 a and 3b.

Fig. 3 A show the working method of the locking electrical socket shown in Fig. 2A -2B.When the pin 54 of plug 50 passes through first When the aperture discharged in lever 22 by locking enters socket 20, it encounters spring prong holder 40, and the spring prong is kept Part 40 is not at vertical direction at this time.When being further inserted into, spring prong holder 40 is applied on it by pin 54 Power deflects to upright position.Then, pin 54 passes through the aperture in spring prong holder 40, and enters contact socket 26, root It is electrically connected according to needing to be formed.When insertion force discharges and when the plug 50 and socket 20 of cooperation do not have axial strain, spring Pin holder 40 is only partially from vertical axle offset.It should be noted that in this connecting structure, in the front end table of plug 50 Almost without interval between face and the socket end adjacent with plug 50 of floor module 24, that is, pin probes into the degree base of socket It is conventional degree on this.

Fig. 3 B have been shown in an exaggerated way the situation for applying axial tension to the power cord 34 of socket 20.It bounces back slightly Movement generates pulling force on spring prong holder 40, so as to increase the angle of lever, subsequent tensioning spring pin holder 40 With the drift angle of pin 54.Then, socket 20 and plug 50 are fully locked in this state.When between release lever 30 and plug 50 When applying axial tension, the position of spring prong holder 40 returns to subvertical position as shown in fig. 3, so as to From 54 release spring pin holder 40 of pin.In release, socket 20 is easy to detach from plug 50.Due to discharging lever 30 It is installed as telescopically sliding relative to floor module 24, and can hold release lever 30 by pinching and discharged from top or side Pin, therefore even if in crowded or limited space environment (such as in data center), also can easily discharge locking machine Structure.

Figure 13 A-13C show a kind of alternative spring prong holder.As described above with shown in Figure 1A to 3B Embodiment in, bite is the flat or semi-flat surface layout along the narrow axis of pin.Aperture is rectangular shape, rectangle Top and bottom include pin on contact position.The power for being applied to these contact points is limited to pin dimensional accuracy and hole ruler Very little relationship.In the embodiment shown in Figure 13 A, under aperture has rectangular top and becomes narrow gradually downwards or is tapered Half portion.The aperture of this design form contacts pin three positions 1100,1101,1104 (referring to Figure 13 A-exaggeration figure), that is, At the top of pin and in every side of bottom.

Since tension and torque is not only amplified, but also the narrow axis by coordinating pin 1103 by the angular displacement of spring prong Wedging effect amplification between two adjacent contact points 1100,1101 at each angle, therefore grip power and may significantly increase.With Pulling force is applied in the hook bolt 1106 of spring stop 1110, it may occur that spring prong holder described in Figure 1A to 1C it is initial Action.After forming contact for the first time at point 1100,1101,1104, when attempting to extract cooperation pin 1103, it is applied to cooperation and inserts Power on foot 1103 can be amplified by the bottom bevel of groove 1100,1001.At the initial stage gripped by spring prong holder 1110 The tension formed around the axial displacement of fulcrum 1105 is significantly enlarged, to be protected in the contact point of cooperation pin 1103 and spring prong The bottom contact point 1100 and 1101 of gripping member applies pressure.Since spring prong holder 1110 is around the tension amplification of fulcrum 1105 Effect, this power are amplified about 10 times.In this way, it can be achieved that about 80 times of total force amplifying function.It should be understood that pass through tune The angle for saving inclined-plane 1100 and 1101 and the geometry for the metalwork 1104 for forming fulcrum 1105 are, it can be achieved that different power is put Big multiple.It should also be understood that amplifying power by change, spring prong holder can be adjusted to and different pin material knead dough layers Optimum engagement.

Since this amplification and spring prong holder, inclined-plane 1112 (Figure 13 C), 1110,1101 and cooperation are inserted Contact area between foot 1103 is smaller, therefore power may be at least up to 30000 pounds/square inch (30Kpsi), so can be really Protect active clamping engagement pin 1103.It is it should be understood that poor to the manufacture of pin using this alternative cooperation pin lock-bit method Different tolerance higher.

Figure 13 B show the method for releasing of this alternative spring prong holder.This method is inserted with aforementioned spring The method of foot holder is similar.Apply release force, bullet to the end of spring prong holder 1111 with the surface of shell 1116 The surface of spring pin holder 1110 can become more perpendicular to cooperation pin 1103.And the contact point at fulcrum 1105 can disengage, And pin is coordinated usually can freely to retract, as the spring prong holder 40 of aforementioned embodiments.But this contact at present (shown in Figure 13 A) 1100,1101 is so that cooperation pin 1103 is locked between them, and the metalwork of pin 1103 is coordinated to exist These points may have occurred smaller flexure.Therefore, cooperation pin 1103 may go back end and be released.As shell 1116 is to spring The surface of pin holder 1110 presses, and the molding inclined-plane in shell 115 starts spring prong holder to push down on, thus to Contact 1100 and 1101 (showing in figure 13a) under lower promotion disengages it from cooperation pin 1103.Finally, entire component from Pin 1103 is closed to disengage.

It should be understood that the shape of spring prong holder (showing in figure 13a) is also beneficial to disengage characteristic.Spring prong is protected The shoulder of gripping member 1107 is arranged as：When force is to discharge on spring prong holder, the shoulder can contact shell 1116 Inner surface.The surface of spring prong holder can cause spring to be inserted towards being rotated further for direction perpendicular to cooperation pin 1103 The entire surface of foot holder 1111 is forced to move down.This action and the action meeting of being combined on the inclined-plane being molded into shell 1115 Lead to the lower pressure taken the initiative on spring prong holder, make lower contact 1100 and 1101 (showing in figure 13a) from Pin 1103 is closed to disengage.

Figure 14 A-15B show a kind of alternative locking mechanism.Figure 14 C show the major mechanical portion of locking mechanism Part.Saddle and strain removing part 1401 are disposed on the plastic connector bottom plate of the socket formed by injection molding.Lock-bit elbow Bar 1402 is inserted into two holes of 1401 one end of saddle.The other end of saddle and strain removing part 1401 is crimp rings, root According to the design of power cord, the crimp rings are clipped in power cord in the position or other appropriate locations for just exceeding the starting point of oversheath End perimeter.If it should be understood that for example, using the material different from bottom plate or other power cord attachment mechanisms for the ease of manufacture Expect to manufacture strain relief mechanisms and clamping device (such as using with metal material of different nature), then by using list Only power cord attachment method (such as crimp rings and strain relief member are separated and then mechanically they have been connect Come), this purpose can be easily carried out.It should be understood that strain relief mechanisms described herein can be with aforementioned other two kinds of guarantors Hold mechanism combined use.

Figure 14 A show the component of saddle 1401 and electrical cord assembly 1400,1407.Electrical cord assembly includes main power line 1400th, electrical interface terminal 1406 and the inner conductor 1407 for being connected to terminal 1406 of said power.Terminal 1406 is in In the blind end of saddle and strain removing part 1401, above-mentioned two component is disappeared by the strain in outer contacting bottom plate (not shown) Except path is arranged along long axis.As needed, terminal 1406 mechanical attachment or can be soldered to saddle and strain removing part 1401, with Realize assembling, extending length or other purposes.During fabrication, lock-bit toggle link 1402 is arranged in saddle 1401, in saddle Between two holes.When release actuating lever 1404 is in the opposite side of face lock-bit toggle link 1402, preloading spring 1403 can press Toggle link.

Figure 14 B show the side view of this component.Outer contacting base plate 1409 accommodates and comprising each component, and In the inside that last outsourcing is molded into preventing note film plastics from entering bottom plate in mold process.Figure 14 B, which are additionally aided, understands lock-bit component Fundamental mode.When the pin for being inserted into plug 1405 is inserted into socket, it enters plastic bottom board 1409, Ran Houjin Enter terminal 1406, finally pass through under toggle link 1402, until it is fully inserted into shown position.If apply to power cord Attempt the tension that it is extracted from cooperation plug, then the tension can be transferred to pin 1405 from power cord, so as to (disappear via strain Except component and saddle 1401) toggle link 1402 is transferred to, and toggle link 1402 is come from the saddle 1401 of the bottom of pin 1405 simultaneously It is pressed by the pressure that electric terminal 1406 transmits towards the top of pin 1405.Toggle link is by spring 1403 towards pin connector 1405 It is inserted into the top precompressed of pin.It is appreciated that can appropriately designed pressing pin toggle link shape, applied with control to pin Chucking power for example, toggle link can have groove, to control the power on pin, makes it not be distorted.Base portion for saddle and match Terminal is closed, can also realize this characteristic as needed.The inserts of suitable shape between saddle/strain relief mechanisms 1401 and with The terminal that the shape of the inserts matches can realize this function.As the power being applied on power cord 1407 leads to the length along component The slight movement of axis, cooperation pin also begins to attempt to retract, and toggle link starts to rotate, and rotating manner causes toggle link that plug is connected The top down pressure of the insertion cooperation pin of device 1405 is connect, pin is more tightly squeezed into terminal 1406, so as to which terminal is squeezed into In saddle 1401.Terminal 1406, pin connector 1405 cooperation pin and saddle 1401 between friction be rapidly increased to Make the mobile degree stopped.Coordinate suppressing action of the pin 1405 on electric terminal 1406 that can also improve the quality of electrical connection.It is existing The pin of pin connector 1405 is locked on saddle and strain removing part 1401, so as to be locked to power cord 1407 On.Figure 15 A are an end-views, show the relationship of involved all components in the locking of component.It is inserted into plug 1405 Pin be located in terminal 1406, and terminal 1406 is clipped between pin 1405 and saddle 1401.

Figure 14 B show to discharge the mechanism that toggle link 1402 is connect with the pin of pin connector 1405.Release lever 1404 other end may pass through entire socket, and be stretched out behind connector or component, and user can operate in the extended position. Other manner also can be used to manipulate release lever 1404, such as the mode shown in Figure 14 D.Include machinery when power cord end cap When the extendable temple members 1412 of joining beam 1408 are pulled back to by user, which can push release lever towards toggle link 1402 1404, so as to which plug-assembly is separated (being fully inserted into depth before 1413 indicating plug of line) from jack assemblies.It here, can The motion range of telescopic segment 1412 is controlled by element 1410 and 1411.The pressure transmission of the other end of bar 1404 is to toggle link 1402 Below, and slightly compressed spring 1403.This action can be such that the bottom of toggle link 1402 is inserted into up towards far from pin connector 1405 The direction rotation of pin, and toggle link 1402 is reduced or eliminated and coordinates the contact force between pin 1405, make cooperation pin along contracting Return direction movement.Then, socket can be detached from plug.System may be designed as：When user discharges extendable temple members 1412, spring 1403 make extendable temple members 1412 be back to locking form.

Figure 15 A are an end-views, show critical piece and the section of the insertion pin of pin connector 1405 On socket locking member.As described above, toggle link 1402 has gone to the position of the pin for the pin connector 1405 that pressing is inserted into It puts.Pin 1405 and press terminal 1406, and the bottom of terminal pressing saddle 1401.It should be understood that with the axial direction of power cord The increase of tension, the downward pressure that toggle link 1402 applies can also increase.By selecting appropriate angle and appropriate part dimension, The amplification factor of power may be about 10 to 1.In other words, 10 pounds of adaptabilitys to changes on power cord can cause to apply about 100 on pin Ft lbf.

It should also be understood that the bottom of saddle and strain removing part 1401 can be fabricated to crown shapes as depicted. When the bottom of the saddle of strain removing part 1401 is pushed by pin, this crown shapes allow saddle and strain removing part 1401 bottom functions similarly to the effect of flat spring.It is transmitted by the toggle link to press on pin with resisting by pin and terminal Power spring combination, the spring of saddle base allows to apply highly controllable and predictable power to pin 1405.Toggle link exists Maximum grip power on pin by spring resistance and Stroke Control.This characteristic can also be used as described below.When being generated on power cord When pulling open the strain of connection, toggle link can increase its pressure on pin, may eventually reach so that among the saddle base (or Under, described in the alternative embodiments in following article) the degree that begins to level off of spring and strain removing part 1401.This A action is so that the distance of the end of the base portion and toggle link 1402 of saddle and strain removing part 1401 increases, so that toggle link 1402 rotations.As the tension on power cord continues to increase, can reach so that saddle and strain removing part 1401 and toggle link The distance between 1402 are large enough to that toggle link 1402 is made to rotate and perpendicular to the degree of pin.At this point, the tab on toggle link 1402 No longer increase any additonal pressure to pin 1405, moved under the tension that pin 1405 can be on power cord 1407 be applied to, and This can be such that plug is detached with socket.It should also be understood that tension when discharging can be predicted reliably, and the strong of spring can be passed through It spends and changes the tension with stroke.This design is to the manufacturing variation of the mechanical part of the connector inserting pin and locking mechanism of insertion There is certain tolerance.It should also be understood that it can reliably preset the tension being connected when discharging under stress.

For this design, Figure 15 A show an end-view of saddle and strain removing part 1401, wherein, power supply The pressure connection terminal of line is in the position far from observer.Have in forward sight coronal spring 1521 described in figure and control connected group The function of point of release of the part under strained condition.In Figure 15 B, show that the coronal spring has for changing coronal spring Intensity and stroke hole 1541.However, it is possible to other means (such as the thickness of material therefor, type or tempering etc.) is selected Control spring function.It can be seen that the position in hole 1541 is located at the underface of the saddle section of saddle and strain removing part 1401, It should be understood that the action intensity of coronal spring is changeable.When not having hole, the resistance to compression pression of the coronal part of spring can reach It is maximum；When hole is larger, the intensity of spring can significantly reduce.By reducing the intensity of spring, mating connector portion can be reduced The point of release of part.Therefore, the holding capacity of locking receptacles can be reliably set as specifically discharging tension.It should be understood that this Kind design can further improve the convenience of manufacture and reduce manufacture cost.Can have for the punch die of punching press strain relief mechanisms Chipware can change the size in the hole 1541 in flat spring, to realize different release tension values by changing the chipware.Also may be used Using the intensity of setting spring and other means of stroke, such as utilize the thickness and shape of material or the other means of utilization. In addition, it also can be used using with consistent or the appropriate type of variable intensity spring (hairpin spring, flat spring, elastomer Spring etc.) other devices press the bottom of the saddle 1401 immediately below toggle link 1402.In this case, saddle is not required to Spring is combined, spring is independently of saddle.This allows to increase adjusts machine by the spring force that factory and/or end user operate Structure, such as screw.As described above, this mechanism can control the intensity and stroke of the spring of pressing saddle, be gripped so as to control The release tension of mechanism.Range can be controlled to adjust, to meet any demand.It is appreciated that it can reliably set release Power is exceedingly useful, this can be implemented without the locking power cord of independent relieving mechanism.Release is by locking mechanism required It is completed during tension level.

Figure 18 C show the enlarged drawing of another possible example of the present invention.When nut 3340 is screwed downwardly tight, position It is driven axially forward under the action of nut 3340 in the tab 3300 on shell 3310.Tab 3300 is in the insertion of component It is pushed forward on to the inclined-plane 3320 in the part in matching socket.Example shown in Figure 18 C is a bull C13, but this Concept and mechanism can also be used in combination with parent part C13 as shown in Figure 18 D.Institute in bull C13 and Figure 18 D shown in Figure 18 C Unique substantive construction difference between the parent part C13 shown is the arrangement form of electric contact, in parent part version, contact base plate 3480 (components typically checked and approved by release mechanism) are molded into power cord end cap.Shell 3470 can Bao Mo to contact base plate On or be fabricated to the individual components being stuck in contact base plate, this is the construction shown in fig. 3d.Other structures can also be used Make method.Geometry, material, position, number and the mechanism of changeable tab 3300,3400 and inclined-plane 3320,3420, Desired position is in the region for ensuring to bear with the maximum pressure on the inclined-plane of cooperation female contact.This to carrying to the maximum extent High retentivity and ensure socket can bear tab 3300,3400 application power without damage it is critically important.Tab 3300,3400 Number can be one or more, and can be arranged so that the retentivity of the mechanism reaches best.They may be disposed so that Toward each other, can not also be relative to each other, arrangement relative to each other can be used for the power for ensuring to be applied on socket to make holding Power maximizes.As shown in the figure, tab 3300,3400 can be intended to exert a force to socket so that the wall of socket is pressurized in tensioning shape State, according to the material of socket, it may be desirable for this.The surface that the wall with coordinating socket of tab 3350,3450 contacts It can be by having one or more materials of appropriate machinery and frictional behavior to be made.The example of one possible example is to use The material manufacture shell 3310,3410 harder, mechanical strength is higher, then the application height friction on tab surface 3350,3450 The elastomeric material of coefficient.For example, this can economically be completed by common note (" sandwich ") molding process.It is appreciated that as schemed Holding mechanism shown in 18C, 18D makes a response to the withdrawal force 3385,3485 being applied on power cord 3380,3480, passes through Power cord 3380,3480 is transferred to the power end of power cord end cap 3390,3490.This, which can be compressed, is commonly used to manufacture power supply The elastomer injection molded material of line causes the end of power cord end cap to be moved slightly towards the direction close to shell 3310,3410, and outer Shell 3310,3410 makes tab 3300,3400 further climb on inclined-plane 3340,3440, and inclined-plane 3340,3440 presses tab 3350th, 3450 contact zone makes its wall with socket more be in close contact, and the friction interlock between plug and socket is caused to act on and is added By force.Therefore, exactly it is intended to the power 3385,3485 that plug is extracted from socket that the wall of holding mechanism and socket is made to pass through friction mutually Interlocking closes, and so as to prevent the extraction of plug, and keeps the electrical connection of matable assembly.Can also change tab 3300,3400 and tiltedly Geometry, material and the mechanism in face 3320,3420 with the power being applied to by limitation on the wall of cooperation socket and are dashed forward Friction interlock between the contact surface of tongue 3350,3450 and the wall for coordinating socket acts on providing programmable relieving mechanism.Limit Friction interlock effect processed can limit the maximum, force that locking connection can resist.When the power for applying the level, plug and socket meeting Separation.As it was noted above, thus can specification maximum, force level, plug and socket to be prevented to be damaged and/or meets correlation Standard, moreover, as it was noted above, user can adjust the range of holding force value by operating nut 3340,3440.

Figure 18 E-18K show another possible example of the present invention, and show and utilize new holding mechanism Another locking means of IEC-13 sockets.It is mainly included with this connector is clamped to fitting type connector (such as IEC- 14) relevant three critical pieces on.It should be noted that this mechanism is not limited to IEC series connectors, also it is suitably adapted for a variety of Connector fit applications, including the use of the connector fit applications of the backplate shell on socket.In this socket with backplate In the case of, backplate can be used as with the friction element of the wall of socket interaction is coordinated to be clamped to realize, and this folder The mode of holding is not depended in the connector middle conductive method utilized in itself.

18E is please see Figure, the inner core of connector 1 in terms of size and electrical interface component by being very similar to traditional IEC-13 The molded assembly composition of (or other standards) power cord end cap socket (female end).The difference is that insulating bag mould have across Shell is passed through two rectangular openings 3551 of enclosure interior.In addition, lock tab reciprocator 2 provides lock made of suitable material Determine tab 3553 and the structure for transmitting power into the shell area of inner core 1 by hole 3551 from locking nut 3.

It is to wedge the top of mating connector under the driving effect of nut by tab 3553 to be locked to mating connector It is realized between bottom outer surface and between the top and bottom inner surface of inner core housing 1.When needing to discharge connection, Nut 3 can be unclamped, this can make tab 3353 actively retract.This is completed by the engagement neck ring 3555 on nut 3, described to connect It closes neck ring 3555 to rotate in the groove 3554 of lock tab reciprocator 2, so as to pull out tab 3553.Other hands can also be used Section is attached to nut 3 in lock tab reciprocator 2, and an example is shown in FIG. 25.This locking means provide Good grip and programmable release force.It, can be maximum by carefully selecting shape, geometry and material therefor Retentivity is restricted within required numberical range.In addition, outer surface (such as the closely appearance of lock tab 3553 of coating Face) optionally there is coating, texture or other designs, to increase the friction matched between combining harmoniously of shell 3551 and socket Power.Plug and power cord end cap during the damage of excessive withdrawal force is connected in order to prevent, release force control to selected number Ability within the scope of value is desirable.This ability is also useful to meeting certain agency qualification requirements.In addition, this side Method makes manufacture become simple, and moving component is minimum.

18F is please see Figure, the sectional view of two critical pieces is shown：Conventional power source line end cap plug (public connector) 1 vertical view and the vertical view of cooperation power cord end cap connector (mother socket) 2.Although plug 1 is as locking electrically connected method Explanation a part description, but it is critical that plug can be standard unmodified plug.Only cooperation socket 2 is with passing The standard socket of system is different, and is unique.It means that the present invention is suitable for the standard plug installed on a large scale, such as The plug used in the multi-gang socket of data center.In worldwide, it is common to use IEC C14 multi-gang sockets come for The electric utility distribution of more than 200V.Conventional male prongs are made of three critical pieces shown in Figure 18 F, that is, packet mould insulator 3561st, the electric connector pin 3563 of connecting line and cooperation comprising necessary conductor 3562.This example belongs to traditional IEC-14 type plugs, but it is alternatively other types using outer pin insulation protective board 3569.In addition pin backplate 3569 is usual It is concentric with pin 3563, and is the clamping object of cooperation socket in application.

The focus of this application is jack assemblies 2, it is included equipped with the chipware of shell 3564 and reciprocator 3565, institute It states reciprocator to include being used as part thereof of lock tab 3567, one of lock tab is shown in the drawings.By It is vertical view, therefore can be only seen the profile of above-mentioned tab in this, but there are two tabs, one on the top of connector Portion, in bottom, each is a component part of molding reciprocator shown in figure component for another.Shown tab is One preferred embodiment, but the method can also be used in combination with other tab numbers, shape and position.Chipware 3564 is at it On be also molded with certain screw thread 3570 engaged with locking nut 3566.The screw thread of this threaded nut and chipware 3564 is matched Work is closed, to exert a force to mobile reciprocator 3565, and axial force is transmitted to tab 3567.

Figure 18 G are the side cross-sectional views of the above-mentioned component in Figure 18 F.It is prominent that this figure more clearly illustrates top and bottom locking The relationship of tongue 3567, and show that they are a parts for reciprocator 3565.In Figure 18 G, the lock of shown jack assemblies 2 Tight nut 3570 has turned to latched position, and reciprocator 3565 is pushed forward, and lock tab 3567 is completely inserted into shell In body and chipware 3564.Figure 18 H are the amplification side cross-sectional views of jack assemblies 2.Tab 3567 is more clearly illustrated in this figure Across the hole 3551 in chipware and housing 3564.Hole 3551 has the conical entrance extending into the cavity of chipware and housing 3564 3571, in this example, when reciprocator 3565 moves from right to left, the conical entrance 3571 causes tab 3567 by court Center line pushes.This example has reciprocator 3565, therefore shown tab 3567 is in releasing position.Tab 3567 is from chamber Body is significantly retracted, and the region in the cavity is made to be subjected to the insertion of the housing of cooperation plug.In order to illustrate this application focus, Inapplicable plug and socket component is no longer described in detail in this.These components include pin and the electric components such as socket and power cord.

Figure 18 I show the jack assemblies of Figure 18 F, wherein, locking nut 206 rotation be to reciprocator 3565 apply to Preceding axial force, and reciprocator 3565 is pushed into tab 3567 in the cavity of chipware and housing 3564.It needs to illustrate herein The relationship of tab 3567 and conical entrance 3571.The combination of taper and conical entrance 3571 on tab 3567 makes 3567 court of tab The center line of component curves inwardly.Figure 18 J show the cooperation of socket 2 and standard cooperation plug 1 in unlocked position. Lower right side shows an enlarged detail, is not done with cooperation plug protective case 3569 wherein more clearly illustrating lock tab 3551 It relates to.When reciprocator 3565 retracts as shown in the figure, the inner wall inclined-plane of tab 3551, chipware and housing 3571 and cooperation are inserted It is hardly contacted between the outer surface of the protective case 3569 of head.

Figure 18 K show cooperation and the locked condition of the combination of plug 1 and socket 2.Nut 3566 has rotated past to force Structure 3565 of answering a pager's call moves forward.Tab 3567 and cooperation plug protective case are more clearly illustrated in the enlarged detail shown in lower right side New relation between 3569.When reciprocator 3565 is forced to move forward as shown in the figure, tab 3551, chipware and housing 3571 Inner wall inclined-plane and coordinate plug protective case 3569 outer surface between significantly contact.As locking nut 3566 is further It tightens, due to the power amplification on the inner wall inclined-plane of the gradual taper and chipware and housing 3571 of tab 3567, tab 151, Radial load between the outer surface of the protective case 3569 on the inner wall inclined-plane and cooperation plug of chipware and housing 3571 is very rapidly Increase.Identical effect also occurs on the opposite side of the protective case of plug and the opposite direction of the side.These opposite forces help In making plug 1 center condition is kept in socket 2.

To sum up, shown in figure is the another kind side for being locked merely with friction (locking) two mating connectors Method.The explanation of the mechanical property of socket shows the unmodified standard cooperation for socket being locked (locking) to same size Mechanism on plug.

The method of this locking electrical connection can easily be made to be adapted to provide for required by concrete application or management organization very much Difference release tension range.The shape of tab, arrangement and geometry and tapered opening and screw pitch are slightly repaiied Change all the coupling mechanism force that " locking " of plug and socket may be coordinated and the type for disconnecting the power needed for the cooperation have different shadows It rings.The simplicity of this design makes it not only consolidate but also convenient for manufacture.The reduction of part count and use completely can castings Material can reduce manufacture cost.

Figure 19-22 shows to lock the mechanism that may include the cooperation electrical connection in the locking connecting structure of the present invention A kind of embodiment.In this embodiment, the mechanism response is intended to 6070 auto lock of power that connection is pulled open certainly Body.Figure 20-22 shows vertical view when holding mechanism is in following state：1) 5000 are fully inserted into；2) under tension completely It is inserted into 6000；3) 7000 are discharged.Figure 19 shows the element of plug and socket and holding mechanism.Figure 20 is shown in plug Connection when being inserted into socket but not applying the power for being intended to that connection is pulled open also.Figure 21 shows holding mechanism 6000 To being intended to pull the plug out of the socket the working method that 6010 power makes a response from socket 6020 on plug 601.Such as enlarged detail institute The holding mechanism 6100 shown makes a response to 6010 power of pulling the plug out of the socket, and elastomer 6050 is forced more by the effect on inclined-plane 6040 Tightly the wall with socket 6060 contacts so that the friction interlock effect between plug 6010 and socket 6020 is strengthened.Therefore, exactly It is intended to the power 6070 that plug 6010 is extracted from socket 6020 that the wall of holding mechanism 6000 and socket 6060 is made to pass through friction mutually Interlocking closes, and so as to prevent the extraction of plug 6010, and keeps the electrical connection of matable assembly.As described above, holding mechanism 6000 can It is made of any appropriate material.Figure 22 shows working method of the holding mechanism when locking Connection Release.When user needs During release connection, user, which can pinch, to hold and pulls shell 7030, and shell 7030 can retract, by the prolongation of shell 7060 bullet Property body 7040 retract 7070 to inclined-plane 7050 downwards, elastomer 7040 is made not recompress, so as to discharge connection.

Figure 23-24 shows to lock the mechanism that may include the cooperation electrical connection in the locking connecting structure of the present invention A kind of embodiment.In this embodiment, the mechanism response is intended to the power auto lock that connection is pulled open itself.Figure 23 be the top side view for the plug 8000 for being combined with retaining mechanism and the side view 8010 and perspective of typical standard socket Figure 80 20.There is the socket finger-like to construct 8030, when finger-like construction 8030 is caught in panel, its locking socket 8020.In typical case, these finger-like construction 8030 is arranged in the clamping socket 8020 independently moulded and in a molding In the mold type socket that 2,3 or more sockets are provided in unit, to snap onto in multi-gang socket.When socket 8020 is inserted into When, finger-like construction 8030 opens, and opening is left in the ontology of socket 8020.In the case of finger-like construction is not provided, manufacture Mold can be transformed in person, constructed or with similar figures with ensuring to provide this finger-like in the single-socket or multi-gang socket of each model The groove or hole of shape and arrangement form, the cost of this transformation is very low, and the certification of management organization is had little effect, is realized To be easy to and inexpensively.Plug 8000 has tab 8040 (being optionally formed as hook shape), when plug 8000 is inserted into When in socket 8020, the tab 8040 can be expanded, and its own is inserted into the opening in the ontology of socket 8020.Tab The location and shape of 8040 end are so as to which the wall transmission itself insertion and to socket is intended to what connection was pulled open Power, but the opening being not passed through on the wall of socket 8020.This can ensure that tab 8020 will not be in the power that connection is intended to pull open Under the action of blocked by the wall of socket, thus plug 8000 and socket 8020 can be separated.This moulding of tab 8020 ensures to lock Tight connection can correctly work, and always can correctly discharge when needed.In order to discharge connection, user, which can pinch, holds shell 805, It is pulled back to, so as to which plug is extracted from socket 8020.

Figure 24 A-24E show that electric contact pin is in the vertical view of the holding mechanism of following state：1) partial insertion (figure 24A)；2) it is inserted into but does not lock (Figure 24 B)；3) it is fully inserted into and locks 9020 (Figure 24 C)；4) it is fully inserted into and discharges 9030 (Figure 24 D)；5) it pulls up, thus disconnects 9040 (Figure 24 E).As described above and shown in Figure 24 A-24E, plug 8000 has Tab 8040 (is optionally formed as hook shape), and when plug is inserted into socket 8020, the tab 8040 can be expanded, and Its own is inserted into the opening in the ontology of socket 8020.In order to discharge connection, user, which can pinch, holds shell 8050, its to 8060 are pulled back, so as to which plug 8000 is extracted from socket 8020, as shown in Figure 24 D and Figure 24 E.Shell 8050 has suitable shape The opening of (substantially rectangular cross-sectional configuration), so that tab 8040 passes through, when shell 8050 is pulled back to by user 8060, rectangular aperture Edge before plug can press tab 8040, so as to discharge plug 8000, it be made to be disconnected from socket 8020.It keeps Mechanism can be made of any appropriate material.It should be noted that this embodiment of the mechanism be easy to it is described above It is used in combination using the version of the manual holding mechanism of user activated.This example carrys out controling shell using aforementioned actuating nut Position and movement.The releasing position of actuating nut can make shell press tab, them is prevented to be engaged with socket, but does not prevent to insert Head is inserted into socket or comes out of the socket.The locked position of actuating nut allows tab to be engaged with socket, so as to the company of locking It connects.This version comes in handy in some cases.

Figure 26 A-C show alternatively possible method power cord being locked in multi-gang socket.Locking mechanism has been tied It closes in multi-gang socket, so as to which each power cord can be locked disposably, and can discharge simultaneously.Figure 26 J are shown by 12 (other types can also be used in the multi-gang socket component 4040 of NEMA (National Electric Manufacture Business Association) 5-15 types socket composition Socket, 5-15 types are used only as an example herein), these sockets are in line, and are assembled into elongated " strip ".It is this Construction is commonly used in electronic equipment rack, commonly referred to as multi-gang socket, will hereinafter use this title.It can be made using the method Any number of socket is made, from one to any number limited by actual conditions.The multi-gang socket of object as the present invention Be unique in that, it is combined with the lockout feature for locking the power-line plug to be attached to multi-gang socket.Socket with Locking or unlocking for the plug of attachment is realized by using the socket head screw 4021 before small tool rotary panel. The actuator must be not necessarily interior hexagonal part or be integrated into component the knob or hand of (or independently of component) Handle or the other devices for driving internal mechanism.It can be the proprietary connection with mating tool, knob or lever Device, for ensuring only to unlock and relock multi-gang socket by the personnel authorized.It can be by motor or electromagnetism The locking mechanism of valve driving, this locking mechanism can be control on the spot (such as controlled by button or switch or pass through peace Full key actuated switch control is controlled, such as by secure digital authentication data key card or security password keypad for vehicle The device of door is controlled by digital cipher card, ID card or other appropriate physical access control mechanisms) or Remote-control motor driving.Remote control can be realized by any appropriate communication mechanism, as needed, this communication mechanism can carry or There is no a security feature, for example, communicated by internet, internal data net or wireless network (either of which can by encryption, The means such as authentication, token are embodied as secure connection) or communicated by any other appropriate mode.

The unique thought of one of the present invention is that the plug of attachment is locked to by simple disposable all sockets of operation handlebar Upper or from attachment plug unlocks the ability of all sockets.In addition, this design allows when component is in the locked position with can The withdrawal force (programmable release force) of prediction extracts the plug of any attachment.(such as insure to meet the requirement of management organization The requirement in quotient laboratory (UL)), this may be necessary.It is public that this design allows the attachment plug of larger change range to manufacture Difference.In addition, due to the simplicity of design, the design of this component can reduce manufacture cost and improve reliability.This design can It is suitable for various types of plugs, is not limited to the example of NEMA 5-15 type plugs.

It is described in detail：

One key Design feature of locked component is unique pin locking mechanism, it can be assembled as random length, tool There is any number of lock-bit point, the number of lock-bit point is corresponding with the number for the socket that multi-gang socket is provided.Figure 26 A are shown often Three basic element of character of a pin lock-bit component.These components may be arranged at each socket, and it is at least one to form each socket The combination of component, but it is equally applicable to each pin lock-bit position of any one socket and all sockets.For electrical isolation The reason of, for each in conductor, component must keep independent.Component shown in Figure 26 A is all-metal property, most Possible situation is made of the metal material with satisfactory electrical conductivity, such as brass, beryllium copper or other appropriate high tensiles are strong Material is spent, but is not limited to these materials.Main electrical prongs receiving element 4001 is shown on the left of figure.It is by machine punch and die Molded part forms.Pin contact chip 4010 is formed by substrate stamped metal material, and is inwardly rolled by the common mode of industry, To provide the cooperation aperture that pin can be passed in and out easily, but very safe be electrically connected can be formed with cooperation pin.It is connect positioned at electricity Hole in stamping parts 4012 after contact 4010 allows the pin of mating connector to penetrate component completely.In first hole just Stamp out another hole in the metalwork 4011 of top.This hole 4011 leaves for the spring of another component of final component Working space.Second component of clamp assemblies is pin bearing stamping parts 4002, it performs practical holding and is inserted at work The function of pin.It is also ferromagnetism steel plate, and must have a degree of brittleness.This is necessary, because in the punching Unitary spring 4017 there are one being formed in casting die.Look at component side view, it can be seen that the metal material of spring 4017 is to left avertence Turn, form arc.The effect of this spring is discussed when assembled component will be described hereinafter.In addition, in this component 4015 There are one hole, which allows the pin of plug is coordinated to pass freely through this stamping parts for middle punching.Shown third component is slotting Foot rear support 4003, it is a simple stamping parts, there is hole 4020, the hole 4020 position at lower aperture 4012 wherein In the relative position identical with pin receiving element 4001.

Figure 26 B show the orthogonal view 4051 and side view after the assembling of above three component 4001,4002,4003 4052.It will be obvious why hole 4011 is necessary in pin receiving part 4001 now.The protruding portion of spring 4017 There is the position do not interfered now.In this figure, additionally it is possible to see, three lower apertures are to just, to allow plug to be attached Engagement pin pass through.

In Figure 26 C, another component is shown, that is, pin, and show representational with single pin 4013 Plug Local map, although the plug with single pin 4013 be not the present invention final component a part, This be used for be set forth in two parts 4052,4053 are locked together during all parts function.Representational plug It is made of with 4053 component of pin pin 4017 and insulating base 4020.It is usually a part for three pin plug components, but It is a component for being alternatively any pin combination.This system can be suitble to the pin of any shape, only need to be each subassembly The shape in aperture is with treating that the required pin of lock-bit matches.Pin receiving unit 4052 is shown, and in side view by main electric mortiser Foot receiving element 4001, pin bearing stamping parts 4002 and pin rear support 4003 form.At this point, electrical prongs contact chip 4010 is also It is not engaged by cooperation pin 4017.

Figure 26 D show the plug 4053 completely into pin receiving unit 4052.Three components 4001,4002, 4003 alignment hole mouth allows pin 4017 to pass through them and enters electric contact piece 4010.At this point, three apertures are substantially right Positive, pin 4017 is allowed freely to be passed through from them.Shown spring 4017 is in relaxed state.

In Figure 26 E, shown pin bearing stamping parts 4002 bears the power applied in a downwardly direction.In this stamping parts The top in aperture applies pressure to the top of pin 4017 now.Meanwhile main electrical prongs receiving element 4001 and pin support punching press The bottom in the aperture in part 4002 applies the reaction force in opposite direction to pin 4017, leads to shear action.Due to pin Relative intensity it is higher, therefore shearing force be only used for lock pin, without it is made to be damaged.Shown spring 4017 is herein When compressed.This allows pin to support stamping parts 4002 with having measurable scope of activities after 4017 initial contact of pin. This is necessary, because the pin size of different manufacturers is different, and the arrangement shape that multiple pin receiving elements are in line Formula needs to compensate the means of smaller manufacturing variation.Spring 4017 is additionally operable to that the power of predeterminated level is allowed to be applied to pin 4017 On, to realize the given vertical range of deflection of pin bearing stamping parts 4002.It simultaneously " is locked " at this point, pin is locked.

Figure 26 F show the multiple above-mentioned pin receiving units 4052 being continuously in line.All three of component 4052 Component repeated arrangement in the form of three one group of stamping parts is a line.Final more pin lock-bit components 4054 are by fitting together Three metal parts form.

Figure 26 G show the component of pin lock-bit more than three 4054 being juxtaposed to each other, and arrangement form causes each hole The arrangement position of pin of the mouth position with coordinating plug is consistent.This arrangement form is not limited to three conductors, moreover, only including The version of one block of lock-bit plate and two pieces of Electrical Contact Plates is only an example of possible version.At least need one piece of lock Position plate component, to realize the lock-bit of plug.The component is conductive and lock-bit sub-component 4055.

Figure 26 H show a kind of possible method that power is provided to pin bearing stamping parts 4002.Note that pin bearing punching The hook end 4020 of casting die is hooked in the perimeter of lobe plate 4022.It is described when the force of bearing hole 4023 to lobe plate 4022 Power can be passed to the hook 4020 of three pin bearing stamping parts.The shape of lobe plate 4022 allows lobe plate relative to pin The hook 4020 of bearing stamping parts carries out a degree of side-to-side movement, to allow to move relevant lateral movement with cam.It is convex Wheel 4024 is maintained at the position in bearing 4025, and is received interior hexagonal part 4027 in this illustrative examples and drives.It is convex In the gap frame that wheel 4024 and 4025 bearing of bearing are described below.Turn when using the tool being inserted into interior hexagonal part 4027 During moving cam 4024, cam 4024 can be rotated around the eccentric axis of bearing 4025.This eccentric motion is passed to camshaft bearing 4002, and in incoming camshaft bearing receiving element 4023, so as to cause the movement of lobe plate 4022.Due to only needing the inclined of very little Turning, the power being applied on tool (or knob or device of other rotation cams as previously described) is amplified manyfold, from And can easily realize makes all plugs keep the power needed for locking.

Figure 26 J show the component of sub-component, that is, insulated receptacle face 4058, conductive and lock-bit sub-component 4055, cam are held The rear shell of multi-gang socket 4040 after row mechanism 4056, cam support C-shaped frame 4057, insulating spacer 4059 and assembling 4050.Although end cap, electrical cord assembly and electric attachments is not shown, they are implicitly included in final component, and pass through biography The mode of system is attached.
